A demon teaching banefull magick?

I would like to get your advice on a spicie topic.
Do you know a demon that teach banefull magick ?
In the handbook, E.A mentionned a demon called Drathalon, but the guy is pretty silent during evocation. In fact he looks like to be more the gun that the shooting teacher.
I also thought about Andramelech. I would like to know your advice ?
